Abstract
A control method of a liquid discharging apparatus includes: a discharge inspection step of inspecting discharge abnormality of a nozzle by a discharge inspection mechanism; a remaining oscillation inspection step of inspecting oscillation of the ink inside a pressure chamber by a oscillation inspection circuit when the discharge abnormality is detected; a first correction step of performing correction which corresponds to the attachment of the resin inside the pressure chamber with respect to the driving pulse when abnormality is detected in oscillation; a re-discharge inspection step of inspecting the discharge abnormality of the nozzle after the first correction step; and a second correction step of performing the correction which corresponds to the attachment of the resin inside the nozzle with respect to the driving pulse when the abnormality is not detected in the oscillation in the oscillation inspection step or when the discharge abnormality is detected in the re-discharge inspection step.
